This is an interesting sort of screen protector for the Touch HD. When the device is off, the protector has a mirror finish, but when you turn on the device, the protector becomes completely transparent. That said, we’re not sure how this protector would fare outdoors, but it may be a good way to increase the wow factor of your Touch HD by making it looks like a space-age shiny communication device. On eBay, they are going for under $10.
